已证实异尖亚科中的异尖线虫属和海豹线虫属线虫可使人类致病。以异尖线虫属所致疾病为多。上述成虫为海中哺乳动物吞食后,钻入胃粘膜表层,其卵随粪便排出,在海水中成熟并孵化成有鞘的第二期幼虫,小甲壳类吞食后,在体腔内蜕皮形成包囊,鱼类再吞食甲壳类,幼虫在内脏或肌肉内再形成包囊,其他鱼可再吞食上述鱼而感染,在鱼类中多次重复吞食的传播过程中幼虫可长至3cm,仅当适宜终宿主进食感染鱼或鱿鱼时,幼虫可继续发育,钻入胃粘膜而完成它的生活史。人进食生鱼后,异尖线虫幼虫可通过消化道随粪便排出,无症状或仅有轻度的胃肠道不适,但不发展为成虫;也可寄生于胃肠道,产生症状,并可引起宿主反应,其临床表现随寄生部位与时间而不同。
It has been demonstrated that Anisakis and Senegalese Nematoda in Anisobiasis can cause disease in humans. Anisakis disease caused by more. The above adult worms swallowed into the surface of the gastric mucosa after swallowing the mammals in the sea. The eggs are excreted with the feces, mature in seawater and hatch into the second larvae of sheaths. After the small crustaceans devour, they molt in the body cavity to form cysts, The fish then swallow crustaceans and the larvae then form cysts within the gut or muscle. Other fish can ingest the above-mentioned fish and infect them. Larvae can grow up to 3 cm during repeated swallows in fish, When the host infects fish or squid, the larvae may continue to develop and penetrate the gastric mucosa to complete their life history. After people eat raw fish, Anisakis larvae can be excreted in the digestive tract with the feces, asymptomatic or mild gastrointestinal discomfort, but does not develop into adults; can also be parasitic on the gastrointestinal tract, the symptoms can be Cause the host reaction, its clinical manifestations vary with the parasitic site and time.
